Bit Range | Default | Access | Field Name and Description |
31:30 | 00b | RO | Reserved (RSVD) Reserved |
29:24 | 00h | RW | Remote Transmitter Post-Cursor Coefficient List 4/Preset List 9 (RTPOSTCL4PL9) Remote Transmitter Post-Cursor Coefficient List 4/Preset List 9(RTPOSTCL4PL9): For Downstream Port: This field defines the post-cursor coefficient List 4 or Preset List 9 to be used for the remote TX in Phase 3. For Upstream Port: This field defines the post-cursor coefficient List 4 or Preset List 9 to be used for the remote TX in Phase 2. When the remote TX has successfully applied the coefficient or preset, the local RX will then perform Receiver Eye Width Margining to check the margin. The list of coefficient or preset is traversed sequentially starting from List 0 to List N, where N is the most significant coefficient or preset in the list. This field is treated as Preset or Coefficient based on RTPCL1.PCM bit. The value of coefficient programmed into this field assumes FS=64. Hardware will scale the coefficient accordingly based on the remote device FS value. |
23:18 | 00h | RW | Remote Transmitter Pre-Cursor Coefficient List 4/Preset List 8 (RTPRECL4PL8) Remote Transmitter Pre-Cursor Coefficient List 4/Preset List 8 (RTPRECL4PL8): For Downstream Port: This field defines the pre-cursor coefficient List 4 or Preset List 8 to be used for the remote TX in Phase 3. For Upstream Port: This field defines the pre-cursor coefficient List 4 or Preset List 8 to be used for the remote TX in Phase 2. When the remote TX has successfully applied the coefficient or preset, the local RX will then perform Receiver Eye Width Margining to check the margin. The list of coefficient or preset is traversed sequentially starting from List 0 to List N, where N is the most significant coefficient or preset in the list. This field is treated as Preset or Coefficient based on RTPCL1.PCM bit. The value of coefficient programmed into this field assumes FS=64. Hardware will scale the coefficient accordingly based on the remote device FS value. |
17:12 | 00h | RW | Remote Transmitter Post-Cursor Coefficient List 3/Preset List 7 (RTPOSTCL3PL7) Remote Transmitter Post-Cursor Coefficient List 3/Preset List 7 (RTPOSTCL3PL7): For Downstream Port: This field defines the post-cursor coefficient List 3 or Preset List 7 to be used for the remote TX in Phase 3. For Upstream Port: This field defines the post-cursor coefficient List 3 or Preset List 7 to be used for the remote TX in Phase 2. When the remote TX has successfully applied the coefficient or preset, the local RX will then perform Receiver Eye Width Margining to check the margin. The list of coefficient or preset is traversed sequentially starting from List 0 to List N, where N is the most significant coefficient or preset in the list. This field is treated as Preset or Coefficient based on RTPCL1.PCM bit when EQCFG1.RTPCOE = 0. If EQCFG1.RTPCOE = 1, the definition of this field is described in the EQCFG1.RTPCOE description. The value of coefficient programmed into this field assumes FS=64. Hardware will scale the coefficient accordingly based on the remote device FS value. |
